Police: Sausalito couple died of gunshot wounds amid trove of weapons

A couple found dead in Sausalito last weekend both died of gunshot wounds, police confirmed Tuesday.

Robyn Jay Chan, 51, and Mara Yvonne Truly, 41, were discovered inside 173 San Carlos Ave. about 2:45 a.m. Sunday after police received reports of gunshots in the area. The couple hosted a party at the home earlier that night.

Investigators found five guns at the scene, four registered to Chan and one that was unregistered, said Sausalito police Chief Jennifer Tejada.

One of the guns was an AR-15 assault weapon, and two of the weapons had high capacity magazines, she said.

Sausalito police did not disclose that both had gunshot wounds until the autopsies were performed Tuesday. Investigators are still trying to determine the circumstances leading to the shooting and whether it was a murder-suicide.

Tejada reiterated earlier statements that there is no apparent public threat of a killer at large. Tejada said the police department is "very appreciative of the exceptional patience and understanding the community has shown" during the past two days, while police kept a tight lid on information during the early investigation.

The investigation is continuing and police planned to conduct additional interviews.
